IMPROVEMENT IN MATS FOR 'PRESSING OIL.

Spec fication orm g part of Letters Patent No. 1 70,886, dated December7, 1875; application filed October 29, 1875.

To all whom it may concern Be it known that I, THOMAS HAMILLEO MURPHY,of New Orleans, parish of Orleans and State of Louisiana, have inventedan Improvement in Mats for Pressing Oils.

The following description, taken in connection with the accompanyingplate of drawings, hereinafter referred to, forms a full and exactspecification, wherein are set forth the nature and principles of theinvention, by which the same may be distinguished from others of asimilar class, together with such parts thereof as are claimed as newand are desired to be secured by Letters Patent of the United States.

My invention relates to that class of woven mats orsqueezers which aremade use of for pressing oils, fats, &c.; and the nature thereofconsists in certain improvements in the construction of the same,hereinafter shown and described.

In the accompanying plate of drawings, in which corresponding parts aredesignated by the same letters, Figure 1 is a plan view, showing themanner in which metallic wire is interwoven with hair, wool, cotton, orhemp rope. Fig. 2 is a perspective view.

Metallic wire, in combination with hair, wool, cotton, or other suitablematerial, has heretofore been used in the construction of this class ofmats for the purpose of insuring the following advantages: rigidity andutility to support themselves when loaded for the press;

increased durability and economy in' keeping the same in repair; lesswear on the bag operated on, and greater ease of manipulation.

The mat consists of two parts, A and B, hinged together at the center,and is formed by weaving wire on all the ribs without crossing thecenter of the mat with the wire.

a designates the rope, which is led alternately over the ribs b and b;thence alternately backward and forward over the ribs b thencealternately over the ribs 1) and b thence alternately backward andforward over the ribs b, and so on until the mat is completed.

The hinge between the parts A and B is formed by those parts of the ropewhich are led from one part to the other, as is clearly shown in Fig. 1.

One or more strands of wire, 0, are led backward and forward alternatelyover and under the ribs b, and between the pieces of rope, until thepart A is completed. The part B- is completed in the same manner.

I am aware that a patent was granted May 19, 1874, to W. H. Orocker formats for pressin g oils, and I claim nothing therein described as myinvention.

I claim and desire to secure by Letters Patent- A mat for pressing oilscomposed of" rope and wire, the wire being woven on all the ribs withoutcrossing the center, as described, and the rope being woven alternatelybackward and forward over the ribs 12 and b, as described.

In testimony that I claim the foregoing I have hereunto set my hand this16th day of October, 1875.

THOMAS HAMILLEO MURPHY.
